UNITED STATES PATENT OFFICE.
JACOB HOFFMANN AND FREDERICK BEISINGER, OF NEWARK, N. J.
IMPROVEMENT IN LUBRICATORS.
Specification forming part of Letters Patent No. 157,992, dated December 22, 1874; application filed August 27, 1874.
To all whom it may concern:
Be it known that we, J ACOB HOFFMAN and FREDERICK BEISINGER, both of Newark, in the county of Essex and State of New Jersey,
.have invented a new and Improved Lubricator for Locomotive Steam-Chests and Cylinders, of which the following is a specification:
The object of this invention is to improve and simplify the style of lubricator described in the Letters Patent of Heinrich Kessler, dated March 28, 1867, and numbered 63,257 5 and our invention consists in so constructing the lubricatorthat it will operate with precision with one valve, where heretofore, and especially in Kesslcrs patent, two valves were required.
In the drawing, which is a central section of our invention, the letter A represents the lubricator-cup, and B its tubular stem or shank. In the'lower part/of the cup, beneath the bottom a of the same, is arranged a chamber, b, for the valve C to play in. This valve tits against a seat, ci, in the bottom a, as shown, and 1s crowded against its seat by a spiral spring, e, that rests on the upper part of the stem B.
As long as the spring e remains effective, the valve C closes the oil-opening in the center ofthe bottom a of the cup A.
The valve C may have a tube, f, with outletholes at the valve-seat, forming a part thereof, and entering the larger tube g, sliding freely therein, the larger tube g being formed by an upward extension ofthe bottom ot' cup A, as clearly shown in the drawing. lf this arrangement is used, the oil is prevented from owing over the valve, except as it is fed by means of the wick h, which extends from the oil in cup A down into the tube f. These tubes may, however, be dis,- pensed with, and the oil allowed to ill the cup and cover the valve. The former arrangement is advantageous on account of the economy it effects in the consumption of the oil; as, necessarily, but a limited quantity can be carried from the outside cup to the tube over the valve by the capillaries of the wick during the period the valve is closedi. e., during the stoppage of the engine, and when it is running under steam. Between these periodsi. e., when the engine is running from previously-acquired momentumthe valve is opened and shut alternately at every stroke ofthe piston. n
Now, if the wick is used, only so much oil is admitted to the steam-chest as has been conveyed by the wick from the cup A into the tube f, which, under ordinary conditions, is ample; but, if the wick and tube are not used, the oil presses constantly upon the valve, and when a vacuum is produced in the cylinder the pressure is greatly augmented,
so that, every time the Valve is opened, oil
Hows into the steam-chest and cylinder in quantities, it may be, more than sufficient. So far, however, as lubricating the chest is concerned, the difference between these two arrangements is immaterial, the valve acting precisely the same in both.
At the top the cup A is closed by a cap, t, in which there is an aperture, j, that can be more orless closed by apivoted lid, l. Through this aperture j the air necessary to replace the oil withdrawn from the cup can enter the latter.
When this lubricator is placed on the steamchest of a locomotive in the manner indicated, the valve C will be held closed by the spring e as long as the piston in the cylinder works with steam, and, also, as long as the engine is at rest but when the engine is caused to run without steam, by the accumulated force alone, the piston D wfill cause suction in the cylinder and steam-chest, and by this suction the valve C will be drawn down, opened, and oil allowed to flow into `the steam-chest and cylinder to lub'ricate the parts in the desired manner. on the cylinder,V` and used on all kinds of engines. The advantage of it is that it only discharges oil when the piston works without steam. Y
We claim as our invention- In a lubricating-cup, the single valve C, kept in its seat by the spring c, admitting the oil into the steam-chest and cylinder through the tube B, substantially as and for the purpose hereinbcfore described and set forth.
JACOB HOFFMANN. p FRED. BEISINGER.
